Stretching the season past the first frost

Why 01/16 isn't a guarantee
01/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/13 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/30 and only about 1 year in 10 sees frost after that.
